Abstract

Procédé perfectionné pour préparer la quinacridone et ses dérivés. On chauffe un acide 2,5-diarylaminotéréphtalique et un catalyseur acide dans un mélange liquide organique non miscible ni avec l'eau ni avec l'éthylèneglycol, l'éthylèneglycol étant présent en quantité d'environ 0,25 à 4 parties en poids par partie en poids de l'acide, 2,5-diarylaminotéréphtalique et le liquide organique en quantité d'au moins 2 parties en poids par partie en poids de l'éthylèneglycol, à une température suffisante pour que l'eau formée en sous-produit dans la réaction s'échappe du mélange par vaporisation. Comparativement aux procédés de la technique antérieure, le procéde selon l'invention utilise des quantités inférieures de solvants faciles à récupérer.
